I can answer general chemistry questions and those specific to the paint, plastic, and resins fields I have worked in. If I can`t give an answer I know is correct, I will say so. I will not answer questions that sound too much like you need to read your assignment. I will try to help you it if you have read it and do not understand it.


I have a BS in chemistry and years of experience in the paint and plastic industries. Part of that was as a manager
in a production facility
